Opus Oils question

Hey all;
Occasional interest in fragrance just blossomed into serious obsession and I'm seeking out truly unique scents.
Is anyone familiar with Opus Oils? I am particularly intrigued by Jitterbug--lemon, honeysuckle, sandalwood and tobacco? Makes me purr just reading the notes.
But I'm also curious about other Opus Oils fragrances and also experiences in purchasing from this company.
Any thoughts are welcome.
Thanks so much!
